Talking Points

Recent interactions between the hosts and their guests.

Carbon removal is not one thing
Q: What practical steps should early-stage carbon removal startups take to get ready for commercial deals and project finance?
Startups should augment their teams with experienced legal and licensing advisors, build both technical and commercial readiness, plan for extended negotiation timelines with corporates, and design adaptable business models that can deliver revenue today while pursuing longer-term, larger-scale projects.
Carbon removal is not one thing
Q: How have financing models evolved for carbon removal as the market matures?
Financing has shifted from generic exploration to more structured, pathway-specific approaches, including project finance and early loss-bearing structures, with involvement from foundations and corporate off-take commitments; the focus is on delivering repeatable cash flows and de-risking early-stage technology.
Carbon removal is not one thing
Q: Can you explain your investment thesis and the makeup of CounterAct's portfolio in carbon removal?
CounterAct emphasizes specialization in carbon removal, evaluating pathways by their unique economics and integration opportunities rather than chasing a single technology; the portfolio includes diverse pathways with a strategy to back those showing practical, near-term revenue potential and opportunities for industrial integration.
Carbon removal is stuck in low earth orbit. Here's how we get out.
Q: What are the main blockers at the CFO level, and how can the industry address them?
CFOs worry about long horizons, risk, and contract certainty; reducing risk through technical readiness, project assurance, standardization, and bankable offtakes, plus a clear, scalable contracting approach, is key to unlocking CFO buy-in.
Carbon removal is stuck in low earth orbit. Here's how we get out.
Q: Why do you describe carbon removal as being in a low-Earth orbit, and what's needed to reach the next phase?
We've built the foundations for an enterprise, but policy, market structures, and risk capital are still not aligned; the five pillars plus stronger standardization and risk-reducing mechanisms are required to move from pilots to large-scale deals.
